Functions and their Inverses

Solution. a) According to the the definition of the inverse function: a = g -1(0) if and only if g (a) = 0. Which means that a is the value of x such g (x) = 0 . Using the table above for x = 11, g (x) = 0 . Hence a = 11 and therefore g -1(0) = 11.

Clear up math equations

I was about to fail in math, doing online school, this apps is improving from time to time! A few years ago it was unable to solve question by scanning handwritings. I really like this app and I use it for my homework I would suggest to anyone to download this app if he /she does not understand some questions their teachers gave them related to maths.

It is a life changer as my grades have drastically went up, really helps not only dose it give you the answers it also shows you and explains the answer thoroughly. They recently introduced a subscription, but it isn't restricting anything.

Find The Inverse Function from Tables

If you triple x, you're also gonna end up tripling y. Inverse variation. You have y being equal to some constant times one over x. So instead of an x here you have a one over x or if you multiply both sides by x you get x times y is
